CHARLIE T. HUGGINS, OF HEMINGWAY, SOUTH CAROLINA.

CULTIVATOR.

Specification of Letters Patent.

Patented Jan. 20, 1920.

Application filed October 7, 1919. Serial No. 328,970.

To all whom it may concern:

Be it known that I, CHARLIE T. IIIIGGINS, a citizen of the United States, residlng at Hemingway, in the county of VVilliamsburg,

State of South Carolina, have invented certain new and useful Improvements in Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cultivator blades, whether they be specifically shovels, sweeps, or blades of any particular kind that are held to the standard by means of a heel pin or heel bolt.

As ordinarily constructed the ground treating element is disposed against the front face of the standard in which position it is secured by means of a bolt, the head of which rests against the front face of the ground treating element while its stem passes through the standard, and is usually provided with an adjustable nut. With this arrangement, the head of the bolt is exposed and in practic forms a lodgment for grass, weeds and other trash. It is the object of the present invention to form the groundtreating element, which I have elected to illustrate as a sweep, with the head of the bolt member concealed and so positioned as to prevent lodgment upon it of the objectionable material stated.

In the drawings:

Figure 1 is a rear perspective view of a sweep plate embodying the present invention.

Fig. 2 is a vertical section through the standard and the sweep, the section being in a plane including the heel bolt, which is in elevation.

Fig. 3 is a transvers section through the standard and sweep, taken in a plane includin the heel bolt, which latter is in plan.

eferring now to the drawings, the body portion 5 of the sweep has its wings 6 and 7 constructed as is usual. The stem or shank is, however, formed materially longer as illustrated. The stem or shank is bent upon itself in order to form the members 8 and 9 having the connecting bight portion 10, the part 9 continuing behind the part 8 and down behind the body 5 to the point of the latter. The side edges of the stem portion 9 are converged at the free end of the portion 9, as shown at 11, so as to register exactly with the front cutting edges of the wings 6 and 7.

The free end portion of the member 9 lies close against the body of the sweep in which position it may be welded or otherwise secured. The portion of the member 9, from the bight 10 to the body of the sweep, is in spaced relation to the member 8, and is provided with a longitudinal slot 12, the sides of which are parallel as illustrated. The heel bolt 13 employed. is of T shape, the

width of the head of the bolt being substantially the width of the slot 12, while the length of the head is considerably more than the width of the slot.

In practice, the bolt is passed with its head through the slot'12 and is then rotated so that its head will extend with its major dimension across the slot to rest against the inner surface of the member 9, in which position the head will be concealed behind the member 8 which is directed forward of the implement in use. The sweep is then adjusted to pass the stem of the bolt through the standard, after which the usual washer and nut are applied to clamp the sweep to the standard. When it is desired to remove the sweep, it is necessary only that the nut be loosened sufficient to permit rotation of the bolt to aline its head with the slot 12 when the sweep may be lifted from place.

It will of course be understood that the sweep may be adjusted to the standard either in conjunction with the bolt after the latter has been engaged with the sweep, or that the bolt may be first engaged with the standard and the sweep then adjusted to it, the nut being then finally tightened.

What is claimed is:

A cultivator ground treating element comprising a blade having a central, rearwardly directed stem bent upon itself with the initial free end portion overlying the rear face of the fixed end portion and its initial free extremity fastened to the rear of the point of the blade, said overlying portion of the stem being adapted to receive means for fastening it to a standard.

In testimony whereof, I aflix my signature, in the presence of two witnesses.

CHARLIE T. HUGGINS.
